nvBrowser is a project aimed to make a fully-editable metadata environment based browser, focusing on research, testing, and privacy.
Caution
This browser is specifically designed for privacy and research/testing purposes. Use of the browser in illegal ways is NOT encouraged. The author(s) of this project are not liable for any misconduct performed using this project's contents.
Note
This project is halted due to priority shift towards IT coursework. Stagnant, for now.

First iteration of the UI for nvBrowser (Subject to Change) (Nov 2025)
nvBrowser extends the privacy-hardened foundation of LibreWolf uses Python as the base to deliver a powerful privacy-centered browser by adding powerful profile management and configurable fingerprinting capabilities. Each profile maintains its own metadata configuration, network routing preferences, and fingerprint resistance settings, enabling users to switch between different browsing identities seamlessly.
- Multi-Profile Management: Create, edit, and switch between named profiles with distinct configurations
- Configurable Metadata: Customize OS name, hostname, user-agent, ISP label, timezone, locale, and location per profile
- Fingerprint Resistance Modes: Choose between Minimal, Resist, or Dev modes for different levels of fingerprint protection
- Network Routing Options: Implementations with PyQt is to be developed yet.
- Real-Time Provenance Panel: Visual display showing active overrides and spoofed values
- Profile Import/Export: Share and backup profiles using JSON format
- Audit Logging: Track profile changes and browser actions with local logs
- Privacy by Default: Built on PyQt6 which is on top of the Chromium browser, that is de-googled.
nvBrowser is designed for legitimate privacy and testing scenarios:
- Privacy Research: Study browser fingerprinting techniques and develop countermeasures
- Web Development Testing: Test applications across different user-agent, locale, and timezone configurations
- Security Research: Analyze how websites handle different browser identities
- Personal Privacy: Maintain separate browsing identities for different contexts
- Cross-Platform Testing: Simulate different operating systems and devices without virtual machines
